Revision as of 20:43, 25 February 2015

This page describes the implementations of the MEGAN (Model of Emissions of Gases and Aerosols from Nature) biogenic emissions in GEOS-Chem.

Overview

GEOS-Chem has used three versions of the MEGAN biogenic emissions. These are now all described on separate wiki pages.

MEGAN v2.0 biogenic emissions

The MEGAN v2.0 biogenic emissions are now obsolete. They were used in GEOS-Chem v8-02-03 and prior versions.

MEGAN v2.1 biogenic emissions

The MEGAN v2.1 biogenic emissions were used in GEOS-Chem v8-02-04 through GEOS-Chem v9-02. They were retired with the advent of the HEMCO emissions component in GEOS-Chem v10-01.

MEGAN v2.1 plus Guenther 2012 biogenic emissions

GEOS-Chem v10-01 and newer versions now use the MEGAN 2.1 biogenic emissions with updates from Guenther (2012); These are implemented throImplemented via the HEMCO emissions component.
